Review: Fits Under Welding Helmet - I've used it a few days while welding and it honestly seems to work very well. Very noticeable difference between welding with and without air quality and breathing wise lol. Fits perfectly under hood, while still leaving room on the ears for ear earbuds or earplugs.

Very happy with purchase and price. ## Features - NIOSH APPROVED: For environments containing certain oil and non-oil based particles - ASSEMBLY INCLUDES: Half facepiece respirator and particulate filter 2091 P100 - HALF FACEPIECE DESIGN: Combines comfort and convenience - REMARKABLY COMFORTABLE: Soft, lightweight facepiece and easy-to-adjust head straps - CONNECTION TYPE: Bayonet - For industrial/occupational use only.
